Abstract

The invention provides an image-processing method comprising steps of: receiving a picture to be processed and a depth map of the picture; de-noising the depth map according to a preset first filter and the picture; further, computing the fuzzy value of each pixel in the picture according to a preset formula, the de-noised depth map, and preset focusing pixel positional information; and performing fuzzy processing on the picture according to the fuzzy value of each pixel and a preset fuzzy processing algorithm to obtain a picture with a depth of field effect. The method first de-noises the picture in order to decrease a noise influence in the depth map, and then computes the fuzzy value of each pixel in the picture. Therefore, a continuously changed picture is obtained after a depth value continuously changed area in the picture is subjected to depth processing, a tomography phenomenon is avoided, and a good processing result is achieved.

Description

technical field [0001] The present invention relates to the field of electronic equipment, and more specifically, relates to an image processing method and electronic equipment. Background technique [0002] With the development of electronic technology, the camera function is widely used in electronic equipment. [0003] In order to highlight the object to be photographed, the depth of field effect is processed on the picture, so that the image of the subject to be photographed in the finally obtained picture is clear and other parts are blurred. [0004] In the prior art, the layered processing method is generally used to process the depth of field effect on the picture. The specific process is: according to the selected focus point (x, y) and the depth map d, calculate the blur of each pixel in the picture to be processed Then, the image is layered according to the degree of blur, and uniform blur processing is performed on each layer. [0005] However, for images with ...
